Design and construction of repetitive transcranial magnetic stimulation based on dsPIC microcontroller

Today, new techniques and methods are tested for diagnosis and treatment ofdiseases in the field of medical sciences depending on the rapidly developingtechnology. In this thesis, dsPIC microcontroller-based repetitive transcranialmagnetic stimulation device's design and construction was performed. Thisdevice could be used to investigate brain function and to determine the braindiseases. It is not require surgical intervention and it uses the painless method.The reason for using the dsPIC microcontroller is to control the systemfunctions with software. In the circuit design, dsPIC control card, whichgenerates switching signals for the stimulating circuit, was designed firstly.After that the design and construction of stimulating circuit and coil wereperformed. This system could be worked with 1 KV DC voltage and it produces1-10 Hz stimulating signals. The constructed system was tested with 250 V DCvoltage and the successful results were obtained.
